MOSCOW (AP) — A well-preserved Ice Age woolly rhino with many of its internal organs still intact has been recovered from permafrost in Russia’s extreme north. Scientists are waiting for ice roads in the Arctic region to become passable to deliver it to a lab for studies. The carcass is among the best-preserved wooly rhino specimens found to date. Recent years have seen major discoveries of mammoths and other animals as the permafrost increasingly melts across vast areas of Siberia because of global warming. Scientists dated the specimen as anywhere from 20,000- to 50,000-years-old. More precise dating will be possible once it is delivered to a lab for radiocarbon studies.
